Arbitration & Mediation

Arbitration & Mediation

Dr. Katherine Simpson, FCIArb, is an arbitrator based in London (33 Bedford Row) and in the US (through Simpson Dispute Resolution).  She has been involved in over 30 international commercial and investment cases chaired by Prof. Dr. Karl-Heinz Böckstiegel, Prof. William (Rusty) Park, and Prof. Dr. Klaus Peter Berger, among others.  These cases had amounts in controversy ranging from US$5 million to US$2.5 billion and have become the most influential arbitration cases of the past decade, including Bear Creek v. Peru (ICSID 14/21) (elaborating the need for a “social license” to conduct business) and UP v. Hungary (ICSID 13/35) (Global Arbitration Review’s “Most Important Award” of 2019, regarding the Achmea Decision's impact on ICSID jurisdiction).

In 2019, Dr. Simpson was invited to join the AAA-ICDR international panel.  She has experience in investor-state arbitration (7 cases), commercial, construction, energy, mining, oil & gas, human rights, financial services, and financial disputes, and those related to joint ventures. She has served as sole arbitrator in international disputes conducted under the Commercial Rules of the American Arbitration Association ("AAA") and has experience in cases conducted under the rules of the International Chamber of Commerce (“ICC”), London Court of International Arbitration (“LCIA”), Dubai International Arbitration Centre (“DIAC”), the German Institution of Arbitration (“DIS”), and the Chinese European Arbitration Centre (“CEAC”).  She has served in ad hoc arbitrations under the United Nations Commission on International Trade Law (“UNCITRAL”) Rules (2010) and in investor-state arbitrations before the Stockholm Chamber of Commerce (“SCC”) and the International Centre for Settlement of Investment Disputes (“ICSID”).

Dr. Simpson is an arbitrator and does not provide barrister services. 



Prof. Dr. Karl-Heinz Böckstiegel (2018):  Starting from her time some eight years ago when she was at Cologne University, Katherine Simpson has helped me in many of the commercial and investment cases I chaired, as Secretary or Assistant to the Tribunal. She proved to be highly efficient in supporting my case management, researching sources, or providing narrative drafts for decisions the Tribunal had to make. Other members of the tribunal and the staff of various arbitration institutions appreciated her work and she was well respected by counsel of the parties. Obviously, over the years, she gained a large amount of experience and I have no doubt that, by now, she could efficiently and successfully serve as an arbitrator.

Prof. William W. (Rusty) Park (2018):  Dr. Simpson has been an excellent Tribunal Secretary and has now doubtlessly arrived at the point where she will provide fine service as an efficient and intelligent arbitrator.




Dr. Simpson is an attorney who is admitted to practice law in Maryland and New Jersey, USA.

She is a Fellow of the Chartered Institute of Arbitrators (FCIArb).

She is listed on the AAA-ICDR international panel roster.
